my OC is at 4.0 ghz, the voltage is set on auto and it goes up to 1.272 when doing a stress test and sits at 0.996 when idle. thanks for all the speedy replies! it sounds like I was worrying for nothing. in the future I would like to push the OC, maybe up to 4.5, what temp would be considered safe? It sounds like mid 60s is nothing to worry about when under heavy load, but what is the point where it should make me uncomfortable? high 70s? early 80s?
My recommendations for a happy Sandy Bridge long-term overclock:
1. Keep the peak Prime95 temps below 75ºC
2. Keep the CPU voltage below 1.4
